Administrators at Texas A&M University were interested in estimating the percentage of students who are the first in their family to go to college. The A&M student body has about 46,000 members. The president of the university plans a speech to an alumni group. He plans to talk about the proportion of students who responded in the survey that they are the first in their family to attend college, but the first draft of his speech treats that proportion as the actual proportion of current A&M students who are the first in their families to attend college. Explain to the president the difference between the proportion of respondents who are first attenders and the proportion of the entire student body that are first attenders. Use appropriate statistics terminology.

Solution

VerifiedThe proportion of the respondents is a descriptive measure about the sample and thus is called a statistic.

The proportion of the entire student body is a descriptive measure about the population and thus is called a parameter (of interest).

The statistic estimates the value of the corresponding parameter and thus will most likely not be exactly the same as the parameter.
